DYNAMIC RESPONSE OF ROCKING MASONRY CIRCULAR ARCHES

Proceedings of the 7th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2019
The behaviour of masonry constructions against seismic actions, very far from the one characterizing ductile structures, is based on the activation of a rocking motion rather than a dissipating mechanism. A strength resource of masonry structures consists in exhibiting rocking behaviour, until a failure condition is attained.

About rock markings and rock art: A response to Rosenfeld

Australian Archaeology, 2002
This debate paper addresses a proposal to exclude from rock art such phenomena as cupules, hand stencils, abraded grooves and finger flutings, and instead to regard them as gestures and call them 'rock markings'. It is argued that this term has already been taken, being the generic name of all forms of markings on rock, that the proposed division is ...

Ground Response Curves for Rock Tunnels

Journal of Geotechnical Engineering, 1983
Calculations of support pressure—tunnel convergence relationships, or ground response curves are used to improve understanding or rocksupport interaction and to aid in the dimensioning of tunnel support elements. Methods of response curve calculation are presented for a tunnel of circular cross‐section excavated in a rock mass initially subjected to a ...

Dynamic response of an opening in jointed rock

International Journal of Rock Mechanics and Mining Sciences, 1998
Abstract A large-scale test was performed on a 0.4 m diameter lined cylindrical opening in a 2 m cube of jointed limestone for the purpose of gathering data to develop and validate computational models for the dynamic response of structures in jointed rock.

Dielectric and acoustic response of rocks

2008
A self-similar model is developed to explain the conductivity, dielectric, and acoustic response of rocks. The model explicitly takes into account the correlations that lead to a zero percolation threshold, and gives the d.c. conductivity of rock (r(0) - σw(0)θm, with σw(0) the d.c. conductivity of the brine, θ the porosity.

The kinetic response of rock to water vapour

Bulletin of Engineering Geology and the Environment, 2004
This paper outlines the need for a description to quantify the natural response of rock to the presence of water. It discusses the change in mass that occurs in a sample exposed to water vapour over time could provide such a description, and the reason for preferring this method over that of immersing samples in water.
